382 Mr. J. J. Walker's 7iotes on Lepidoptera 



Satnrnia pyri, L, — Apparently common throughout 

 the region. I have had many specimens brought to me 

 at Gibraltar in April and May, and have found the 

 cocoons at Tangier in the winter. On June 28th, 1888, 

 I observed the full-fed larvae in large numbers on willow- 

 bushes and fruit-trees at AlgeQiras. 



S. carpini, L. — Only met with in the cork-woods, 

 where it is very abundant at the end of March (the 

 earliest date on which I have seen it on the wing being 

 the 6th). The larva is also common there in May on a 

 variety of plants, but it appears to have a preference for 

 the yellow-flowered Helianthetyium halimcefolium . 



Lasiocampa trifolii, L. — Not often seen on the wing, 

 but common in the larva-state at Gibraltar and Tangier ; 

 at the latter jjlace feeding chiefly on the single-seeded 

 white broom, Retama monosperma, L. I have taken the 

 male imago at gas-lamps in September at Gibraltar. 



Clisiocampa nenstria, L. — Common in the larva-state 

 at Gibraltar, and near AlgCQiras I have seen the oaks 

 almost defoliated by the ravages of the larva in the 

 beginning of June. The imago appears about the 20th 

 of that month. 



Megasoma repandum, Hiibn. — This fine moth appears 

 to be not uncommon at Gibraltar, also at Esmir, the 

 larvae feeding on various Leguminos(8. I found a female 

 on the Eock of Gibraltar on August 6th, 1888, which 

 laid a few eggs ; the larvae resulting from these fed uj) 

 well on Lotus, and produced fine imagos in November. 

 I also obtained a pupa at Esmir on March 1st, 1889, 

 from which a very fine dark-coloured female emerged on 

 the 20th of the same month. 



Pygcera hucephala, L. — Found in the larva-state on 

 oaks {Quercus lusitanica) near San Koque; also pupae 

 in the sandy soil at the foot of these trees. Imago bred 

 March, 1888 ; these w^ere very large and fine, the expanse 

 of wings being quite 3 in. (76 mm.). 



Cerura vinida, L. — The cocoons (mostly empty) of this 

 moth were not rare on poplar-trunks at Tangier, but 

 only one imago was bred (May, 1888). This is a small 

 and very darkly suffused male, bearing a close resemblance 

 to specimens of D. vienciana, Moore, from the Hima- 

 layas, in the National Collection. 



C. bifida, L. — Occasionally found in the larva-state, 

 or drying its wings on the trunks of poplar-trees, on the
